Title: firefly-rk3399: Boot from SDMMC not working
Hi,

I've burned images into eMMC and it's booting fine. then I have burned on SDMMC card and inserted into TFCARD reader on board.

The bootlog still shows booting from eMMC and hang at bootloader level, here is the log[1] and firefly-rk3388 claims that it support SDMMC boot [2], if So Do I miss anything.

Please let me know how should I boot from SDMMC?

the loader of the SDMMC is not as same as the one of EMMC
so, please use this one if you want boot on SD .
